Application board 3 for the VM2 series of controllers is intended to implement as many interfaces as possible
to allow you to explore the capabilities of the VM2 controller range.
•
Graphics Display interface
•
USB Host: removable storage using memory sticks, etc.
•
USB Device: access to internal Flash Filing System
•
Ethernet
•
Memory card socket (microSD)
•
2 off RS232 serial ports

Page 2: What You Will Need
Unpacking You should have: • Application Board 3 What you will need To start using the application board you will also need: • VM2 or VM2D Controller (5900 or 5907) • 7.5 - 12VDC, 4 Watt power supply. (You can use more than 12VDC with caution.) •... - Page 3 * - These pins are shorted together at each port. There is a resistor position (R5) to pull SerialPort 1's CTS input high if you want the VM2 to be able to 'talk' when there is no serial lead supplying a hardware handshake signal to the Application Board. However it is usually better to overcome this problem in software by turning off hardware handshaking.

Page 4: Keypad Function
The board has a socket for microSD or microSDHC cards. The memory card is intended to provide permanent storage for the system, and should not be removed or fitted while the system is running unless you make provision for this in your application code. Note that, on this board, power to the memory card is controlled by Channel $35. - Page 5 Configuration This is done for you in the default startup procedure, so you don' t have to put it in your code: MAKE net I2CBus This command shows what's connected to the I2C Bus: PRINT net ; print out a list of all devices connected to the I2C Bus.

CAN Bus Links: LK13 and LK14 – link pins 1-2 on both. LK 7: Bus Termination Resources used: CAN(notUSB) switch set to ON (disables USB subsystem, enables CAN Bus) The USB Device and CAN Bus cannot be used at the same time. This board is fitted with a SN65HVD230 CAN Bus driver device allowing the VM2's CAN module to interface with CAN Bus systems. -

Note: The speaker is too small to reproduce lower frequency sounds unaided, but the addition of a baffle of some kind improves it considerably. Given the layout of the PCB, the simplest baffle you can make is a small paper cone (25 to 50mm long), with some Blutak or similar to seal the narrow end to the speaker. The bigger the baffle the better the low frequency sound will be. - Page 9 If this column is blank then the channel may be used immediately.
